Green Seaweed Gallery

Brightly colored green seaweeds, once relatively uncommon in
intertidal zones on this Atlantic coastline of Nova Scotia, are now increasing
in prevalence here. There appears to be a global trend of these sorts of algae
species increasing. In some areas (Hawaii, France) 'green tides' have become a
major nuisance as tons of these fine green growths have been washed onto
beaches. Green 'mats' now cover the bottom of bays. This change is generally
attributed to nutrient overloading of coastal seawater. But here we see the
green growths also increasing in very clean areas, while the older brown and red
algae species appear to be suffering from nutrient shortage.
